produce the correct synthesize

Answer 1

N-Bromosuccinimide tertiary carbon Br more reactive Br2, hv NaOMe, MeOН Br- NBS, hv radical elimination -Br bromination allylic bromination ÓMe NaOMe, MEOH H2, Pd/C OMe Nucleophilic substitution -OMe reduction of the double bond In the first step, radical bromination of the alkane give tertiary bromide which on elimination reaction give alkene product. In the next steps, allylic bromination followed by nucleophilic substitution and reduction of the double bond give the desired product as shown above. Sodium methoxide (NaOMe) can act as both nucleophile and base.
